on thc line 8 8 of Fig. 5, ol'l means for preventing reverse rotation o'l the spools, Fig. 9 is a section Ol the spool shown in Fig. 5, taken on the line 9-9 of Fig. 5, Fig. 10 is a section of the spool shown in Fig. 6, taken on the line 1.0-10 of Fig. 6, Fig. 11 is an inverted plan view, partly in section, of the bracket in which the spindles 'for the spools shown in Fig. G are supported, Fig. 12 is a 'fragmentary side elevation ol the same, Fig. 13 is an elevation, partly in section, of a socket wrench used to adjust the bracket shown in Fig. 11, vertically on the main vertical operating shaft of the. machine, Fig. 14 is a horizontal section o1 a drum for containing loose or unmanu'lactured textile fibers during the dyeing of the same in the machine, and Fig. 15 is a vertical central section of the lower portion of the same, showing the manner ol mounting the same on the spindles upon which the spools are mounted when skein yarn is being dyed.

Referring to the drawings, is a tank o" vessel adapted to contain the dye liquor \'rcrtically arranged in the vessel 2() is the. main operating shal't 2l, which may be driven in any suitable manner, but is shown provided with a worin wheel 2') which may be actuated by a worin, not shown. Shaft 21 is journalcd at its upper cud in a bearing 23 mounted in a suitable lrame work 24 extending upward from the vat or vessel 20. The shaft 21, is journalcd in bearing 23 in such manner that it may be slid vertically therein to raise the carried parts out of the dye liquor contained in the vessel 20. For this purpose also the upper end of shalt 21 `may be provided with an eye 25 lior engagement with the lil'ting` amiaratus, (not shown). The lower end oll shal't 21 is liournaled in a lioot step bearing 2G, shown in section iu Fig. "i, the upper portion oll bearing 2G being prelierably made flaring` so as to guide the shal't 21 to its proper position as the saine is lowered into place.

Fixedly secured to shalt 21 in such position as to be beneath the surface of the dye liquor when shaft 21 is in its normal operative position in the vessel 20, is a bracket 27 which carries a series of radial spindles 2S, 'lixedly secured therein. VUpon cach spindle 28 a spool 2l) is loosely mounted so as to be capable of rotation thereon. ',lo the outer .llangc ol each spool 29 is secured a star wheel 30, so arranged as to encounter, during the rotation el' shal't 21, the haver end ol a lever 31 which in the normal operation of the machine acts as a stop to cause the rotation of spools 29 step by step as each arm of a star wheel encounters said lever 31. ln the event of any of the spools 29 being prevented from rotating on account of the yarn becoming entangled or from other causes, it is necessary, to prevent breakage, to permit the star wheels to pass without being operated. For this purpose, the lever 31 is pivoted at 32 and is held in its normal position against a stop pin 33 by means of a spring 34 of such power as to hold the lower end of lever 31 against displacement by the star Wheels under normal conditions of operation. Should however any of the star wheels be prevented from rotating as before stated, then the lower end of the lever 31 will be displaced against the tension of spring 34 and the star wheel allowed to pass. W hen this occurs however it is desirable that some indication be had of the improper conditions existing and for this purpose the upper end of lever 31 is provided with a leaf spring 35 carrying a hammer 36 at its free end which is adapted to strike a bell 37 arranged in the path of the hammer 36 in such manner as to cause an audible alarm to be sounded as the lever 31 returns to its normal position after it has been displaced under the conditions stated. To prevent reverse rotation of the spools 2.9 from causes which will hereinafter be more fully set forth, the inner flanges of the spool 29 are each provided with a pawl 3S which engages with a ratchet wheel 39 mounted and secured against rotation on each spindle 2S.

Slidab'ly mounted on the lower portion of the vertical shaft 21 is a bracket 40 in which are carried a series of radial spindles 41, arranged one under each spindle 28 carried by the upper bracket 27. Loosely mounted on each of the spindles 41 is a spool 42 which is capable of free rotation on its spindle, each of the spools 42 forming in connection with the spools 29 arranged above it, a pair of spools over which skeins of yarn are adapted to be carried in the vessel 20 for dyeing. The lower bracket is keyed against rotation on the shaft 21 by means of a key 43, but is capable of vertical adjustment thereon. For the purpose of this adjustment the shaft 21 has a rack 44 cut in it, which rack 44 is engaged by a gear wheel 45 mounted on a shaft 46 which is journaled in bracket 40, so that by turning the shaft 46 and its gear 45 the bracket 4() can be raised or lowered to any desired position on the vertical shaft 21. One end of gear shaft 46 is made square as at 47 for engagement by the square socket 48 of a wrench 49 when it is desired to turn the same for the purpose stated. To lock the bracket 40 at any given position on the shaft 21 there is provided a pawl 50 carried on a shaft 51 also j ournaled inthe bracket 40, the

arrangement being such that the pawl normally engages the gear 45 and is held in such position by means of a spring 52 to lock the gear against rotation. The end of awl shaft 51 adjacent the square end 47 of shaft 46 is provided with a i'inger 53 having an inclined surface 54, the arrangement being such that when the socket wrench 49 is placed on the square end 47 of gear shaft 46 the finger 53 will be pushed aside and by thus slightly rotating pawl shaft 51 causing the pawl 50 to be lifted out of engagement with gear 45 to allow the same to be turned by the socket wrench 49 and thus allow the bracket 40 to be moved to the desired position en the vertical shaft 21.

The operation of the machine as thus far described is as follows:-The vertical shaft 21, with the parts carried thereby, is first raised and held in its raised position. to hohl the spools out of the dye liquor contained in the vessel 20. rlhe skeins of yarn are new mounted on the spools by first placing them Y on the upper spools and then over the lower spools, the lower set of spools being then adjusted down on the vertical shaft 21, in the manner hereinbefore indicated to thereby slightly tension the skeins between the pairs of spools. The vertical shaft is now lowered into the vessel 2() to cause the yarn carried by the spools to be immersed in the dye liquor. Shaft 2l being now rotated, as the star wheel 3() olI each spool 29 encounters the lower end of lever 31, the spool will be rotated step by step on its spindle to cause the portion of the yarn which was in proximity to the spool to be advanced so that all portions of the yarn will be evenly and uniformly subjected to the action of the dye liquor. lt will therefore be understood that the upper set of spools may be considered as driving pulleys, the skeins of yarn constituting belts, and the lowerset of spools constituting idle driven pulleys, over which the yarn passes as it is also rotated in the vessel about the main vertical shaft 21. For the purpose of securing a better hold on the yarn the upper set of spools 29 are preferably made square in cross section as shown in Fig. 10. ln the event of the spools being prevented from rotating from any cause, the device shown in Fig. 7 will be brought into play as hereinbefore described. The yarn being somewhat elastic and the spools being loosely mounted on their respective spindles, it is possible that the ascending portion of the yarn over the spools might be stretched as the star wheels are actuated and to prevent a reverse rotation of the spools from this cause the j )awls 3S and ratchets 39 are provided, the arrangement and construction and operation oll which are hereinbel'ore described. The vertical adjustment of the lower set of spools in addition to permitting the skeins of yarn to be placed on the spools over the flanges thereof, also serves to allow various sizes or lengths of skeins to be dyed in the same machine.

wWhen it is desired to dye loose or umnanufactured textile fibers such as cotton or wool in the machine, the s ools are removed from their respective spindlfes and drums 55 placed thereon as indicated in Figs. 1, 2, 3, and 15 of the drawings. The walls of the drums 55 are perforated as at 56 and are provided on their interior with a series of prongs or spikes 57 to maintain the material in a suspended condition in the drums. One portion 5S of the cylindrical walls of the drums is hinged as at 59 to constitute a door for the insertion and removal of the material. To mount the drums 55 on the spindles, each end of each of the drums is provided with a bearing 60 having studs 61 ournaled therein, the studs 61 forming an axis of rotation for the drums 55. The studs 61 are secured in side extensions 62 of sleeves 63 which are slid on the spindles 2S and 41 at the top and bottom respectively. It will thus be seen that the drums 55 are free to rotate on their axes and to insure this rotation they are provided at one end with a gear 64 which is arranged to mesh with an internal gear 65 which may be fixedly or removable mounted in the vessel 20. The drums 55 will therefore not only rotate about the vertical shaft 21 but will also have an additional rotation about their own axes to thereby insure a thorough permeation of the dye liquor through the material contained within them.

Vhat we claim as new and desire to secure by Letters Patent is:

1. The combination of an open unitary dye containing vessel, a vertical shaft revolubly mounted therein, two series of spools carried by said shaft and extending radially therefrom within the dye containing vessel, one spool of one series constituting with a spool of the other series a pair over which skeins of yarn are adapted to be mounted, the upper series of spools being fixed to the revoluble shaft and the lower' series of spools being simultaneously vertically adjustable thereon, and means located near the top of said vessel for rotating said spools on their individual axes during the rotation of the vertical shaft.
